Question

这是我迄今为止为实现它所做的代码。

public void creditcardPayment(){
APIContext apiContext = new APIContext();
        String accessToken = "";

        try {
            accessToken = new OAuthTokenCredential(CLIENT_ID, CLIENT_SECRET,
                    sdkConfig).getAccessToken();
        } catch (PayPalRESTException e) {
            throw new PayPalRESTException("ACCESS TOKEN ERROR"
                    + e.getLocalizedMessage());
        }

        System.out.println(accessToken);

        apiContext = new APIContext(accessToken);
        apiContext.setConfigurationMap(sdkConfig);

        CreditCard creditCard = new CreditCard();
        creditCard.setType("visa");
        creditCard.setNumber("4204359776052315");
        creditCard.setExpireMonth(3);
        creditCard.setExpireYear(2019);
        creditCard.setFirstName("ppashish");
        creditCard.setLastName("pal");

        CreditCard createdCreditCard = null;
        FundingInstrument fundingInstrument = new FundingInstrument();
        List<FundingInstrument> fundingInstrumentList = new ArrayList<FundingInstrument>();

        try {
            createdCreditCard = creditCard.create(apiContext);
            String ccId = createdCreditCard.getId();
            System.out.println(ccId);

            CreditCardToken creditCardToken = new CreditCardToken();
            creditCardToken.setCreditCardId(ccId);
            System.out.println(creditCardToken.getType() + " last 4");

            fundingInstrument.setCreditCardToken(creditCardToken);
            fundingInstrumentList.add(fundingInstrument);

        } catch (PayPalRESTException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            throw new PayPalRESTException("INVALID CARD"
                    + e.getLocalizedMessage());

        }

        Payer payer = new Payer();
        payer.setFundingInstruments(fundingInstrumentList);
        payer.setPaymentMethod("credit_card");

        System.out.println();

        Amount amount = new Amount();
        amount.setCurrency("USD");
        amount.setTotal("3");

        Transaction transaction = new Transaction();
        transaction.setDescription("creating a payment with saved credit card");
        transaction.setAmount(amount);

        List<Transaction> transactions = new ArrayList<Transaction>();
        transactions.add(transaction);

        Payment payment = new Payment();
        payment.setIntent("authorize");
        payer.setPayerInfo(new PayerInfo().setPayerId("MD44W3Z67ZQZ4"));
        payment.setPayer(payer);
        payment.setTransactions(transactions);
        Payment createdPayment = null;

        try {
            createdPayment = payment.create(apiContext);
        } catch (PayPalRESTException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            throw new PayPalRESTException("TRANSACTION FAILURE..."
                    + e.getLocalizedMessage());
        }

        System.out.println(createdCreditCard.getId());
        System.out.println(createdPayment.getId());
        System.out.println(createdPayment.getState());
        Iterator<Transaction> v = createdPayment.getTransactions().iterator();

        while (v.hasNext()) {
            Transaction ttt = (Transaction) v.next();
            Iterator<RelatedResources> v1 = ttt.getRelatedResources()
                    .iterator();
            while (v1.hasNext()) {
                RelatedResources t = (RelatedResources) v1.next();
                System.out.println(t.toJSON());

            }
        }

}

我在catch块中处理异常，堆栈跟踪如下：

我的问题如下：

我将如何获得异常错误代码和消息（错误代码：400，名称：VALIDATION_ERROR，问题：值无效
如何通过交易中出现的基本问题通知买家有关用户友好的例外情况..

在此先感谢，我是异常处理的新手。希望得到积极回应

REST API报告您传递的信用卡号无效。我要仔细检查以确保您发送了您期望的内容以及它是有效的号码。在现场，它应该是一张真正的牌。在沙箱中，最佳做法是使用与沙盒测试帐户关联的其中一个数字。

如果您仍然认为问题出在PayPal上，请在https://ppmts.custhelp.com/提交一张票，并在错误中报告debug_id。然后，支持代理可以查看此故障的具体细节。

使用paypal中的错误代码和错误描述跟踪异常详细信息
